Need help setting a price for a used 2014 HotSpring NXT Envoy. The hot tub belongs to my grandmother and due to health issues she can no longer use it and wants to sell it. The spa is great condition, looks brand new and everything works. I told her I would help her it but wasn't sure what a fair price would be for it. I would really appreciae anyone who could tell me what they think is a fair price.
